When does my BMW X4 generate a loud noise?
One way to identify a noise from your BMW X4 is to identify when it occurs. Indeed, some trouble can be linked to components that are only stressed under certain circumstances. It is this approach that we will focus on in this first part.
Loud noise BMW X4 when accelerating
Loud noise on BMW X4 that appears when you are accelerating can be symptomatic of different failures. Indeed, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will create a much higher noise than during normal process. Moreover, it is also highly plausible that loud noise on your BMW X4 is in connection with a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my BMW X4 is stopped
If your BMW X4 makes a loud noise while not accelerating, engine on, the issue may be in connection with poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.

The loud noise comes from the wheels of my BMW X4
As we have seen before, loud noise from the wheels of your BMW X4 may be in connection with two main disorders. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So consider to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case replace it or them quickly. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your BMW X4 that is the trouble, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your technician to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my BMW X4
In case you have discovered loud noise as coming from the engine of your BMW X4, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with a compression loss during the engine ramp-up phase, so you should experience a power loss during your acceleration. If the loud noise on your BMW X4 is related to air intake, the check will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two trouble, take your vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have noticed comes from the exhaust pipe of your BMW X4, it is highly plausible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your BMW X4, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm this, get help from someone who will stand under the car while you accelerate to find the exact area of source of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
